An

arm J2 of the journal J extends through a suitable slot in the spindle II, and is toggled to a bell-,crank J', that is fulcrumed tothe rear portion of bracket I, and is' provided at its outer end with a roulettej, that is heldin crumed to the bracket I and kprovided 'at its' impingcment against a cam-wheel L on the shaft D by means of a spring f, arranged onfa pimp, projecting` from fa plate'j, that' l A l the peculiar seamabove referred to no roekpreferably for'rnsjpart of said bracket I.

Surround in g the head Il' is a friction-brake M, on'eend of whichis secured to the plate 7" and its other 'end provided with 'a pivoted free end 4with a roulettejm, `that impinges against acam-wheel 0 ony the shaft D, the

last-named bell-crank and cam-wheel being arranged just above like parts that serve tooperate `the beading-roll K. .Avertical shaft the one K, and these beading-foils may be multiplied when it is `=desirable to give the vesselsmore thanone bead. The shaft P alsoearriesja pulley Iv', that isbelted to another pulleylfiony the spindle E, this construction serving to compensate for any undue friction; of the parts and insure the rotation of the'` roll K in case said roll is tight on its shaft; butI have shown said roll as loosely mounted, and, if desired, the belt-and-pulley mechanism may be omitted.

A shclfA"`on thc'standard has a verticallydepending portion A4, to which latter is cast or otherwise secured a box Q, in which is `fulerumcd a block R, having removably secured thereto and .laterally adjustable thereon a vdependingflange S of a bearing S for the journal '1" of a level', head, or bell-crank T, one arm of which latter carries rolls or `i'ormersh: 7c', for making the seam described and claimed in my patent, NaI-359,826, issued March 27, 1887, this seam consisting of flanges.

on the Ic over of the vessel spanning the rim of the body, thefthree thicknesses of metal being bent. at an angle, leaving the outer edge of thev cover projecting over and clasping the curve ofthe adjacent rim of the body, whereby the necessity of the soldering is avoided. The other arm of said bell-crank is toggled to an adjustable rod U', that connects with a sliding-plate U, that lits in a guide-piece U2, havring adepeuding lsleeve U. surrounding the shaft D. v

The sliding plate U is provided 'with a lug plate U..

a spring k, Aand while the 'fs'eamingirolls k 7o' are shown at right anglesl toeaeh other they may be otherwise disposed to s uit the character ofthe work, and I may also mount the roll k on an eccentric shaft similar to thel one J shown in Fig. 3. The box Q, block R, and sliding plate U are similar in lconstructit'in and arrangement to like parts -in my'patent,.No. 382,499; but the rack, its pinion, and connections for o erating thelatter parts have been omitted 1n this instance, for the reason A that in,making in'g motion is necessary, and lto hold the block R in its fixed position .I use a pin o, (shown in Fig. 1,) that passesthrough a suitableaperture in the box Q to enter a. corresponding aperturein said`.block. y

At any tme when it is desirable to doubleseam the cover-pieces to the vessel-bodies I mayemploythe head shown and described in my said patent, No. 382,499, place a rack in the guides R' of the box Q, and make the proper'z connections with thg cam-wheelgapdsliding p Although I have not shown a rearwardlyprojecting arm asbelonging to .the block R and a cam-wheel .o n the shaft D to operate said arm, it'will be understood thatwhen l'using the doubleseeming head above re ferred to said Varm and cam-wheel are nec- Y'y- In Fig. 8 I show a head comprising adisk W, provided with a series of the seaming-rolls ieg k k', arranged in successive pairs, as shown by v full and dotted lines, said rolls being similar in construction andrelative action as similar parts shown in Figs. 1, 6, and 7. The diskW is loosely journaled on the stud W', projecting from the outer arm of the bell-crank T, and it may be arranged ineither `a vertical or horizontal plane, as found most desirable.

I provide the outer face of the disk W with a ratchet W2, that comes in contact with a Vpawl W3, pivoted to an arm VV, that is A rigidly connected to th'e bearing S of the bell- A crank, and by this arrangement of parts I 'partially rotate said head each time the same is tilted or drawn away from thc vessel by the movement of the cam-actuated sliding plate U,'having the rod-connection U with said bell-erank.

The means just described are the ones 'pref-V erably-employed for causing a partial rotation of the disk W; but it is obvious that other suitable means may' be used for the same purpose.

By the employmentof a head such as I have j ust'described the wear is equally distributed ena series of 1 seaming-rolls arranged in successive pairs, and. in some instances, where it may be found desirable .to make the seamA tighter than can "be done withone pair of rolls,` the groovein-.the roll 7c ofthe next succeeding pair may be adapted for such tight-V ening ofthe seam andthe cam V provided with a contour that will serve to tilt 'the head `at predetermined intervals, whereby the latter set of rolls will be brought into action at the proper time. In orderto prevent any possible rotation of the disk W when the, rolls k lo come in contact with the vessel, Imay employ any suitable stop mechanism-,and in Fig. 1 3 (a section taken on line a: Fig. 11) I have shown one form of such mechanism, thatconsists in providing said dislcywith a series of depressions similar to the one r and corresponding in number with the teeth in the ratchet W 'and ythe bell-crank T,with a hollow projection s, in which latter Iloosely arrange a pin that has a reducedportion s', surrounded by a spiral springt, the larger portion s2 of saidlpiu being 'beveled at its end tocorne in contact witha corresponding lug l'aon the bearing s for the .journal of said bell-crank when the latter is tilted toward thevessel. When the pin and lug come incontact, the former'is pushed in against the spring t toY engage the ii rst one of the depressions r that cornes in its path to thereby lock the disk W, When thescanning-head is `tilted back away from .the vessel, the locking-pin` il. carried therewith away from the lug ju., and the expandingorce of the spring t forces said pin out of engagement with the disk that carries the seamingrolls.

In Figs. 1l` and 121 show a variationof the circular head shown in Fig. 8and.heretoforel described. 'lhis variation consists in omittingall but one of the rolls marked k', the latter be'ng principally employed for bending down the llange of a cover-piece', against the body of a vessel. The roll k in the latter form of head is journaled in an arm T2, that forms part of the bell-crank, and thcI several rolls lo' are successively brought into operative relation with the one irst named by the intermittent partial rotation of the disk W, actuated as above described. In both styles of the .seamingdxcads shown'y by Figs. 8, 11, and l2- it will be understood that I may provide the disk W with supporting-wheels 7c, similar to the one described in vconnection with Figs. 6 and 7, and both these heads may be brought in and out ot' contact with the vessel by a hand-leverinstcad of being automatically actuated,'as above-described.

In Figs. 9 and 10 I show my seaming-rolls k 7o' and pivoted supporting-wheels la as ap plied to a revolving head to operate upon a fnon-revolvin g vessel. In this instance I screwthread or otherwise rigidly secure a circular part Y to the extended hub e of. thegear E', and in this circular part I arrange one ormore pairs of the seaming-rolls 7c 7c' and corresponding supporting-wheels k2, said arrangement ofthese Alatter parts being vprecisely similar to 7c that shown in detail, Figs. 6 and 7.

A spring Y is arranged in the bore ofthe gear-hub e to encircle the spindle E and exert its pressure thereon in a direction toward 4the vessel to be operated upon, the movement of said spindle being limited by means of a col lar c, adjustably secured thereon. v `At any timefit may be desirable to .rotate the vessel without operating on it by the rolls of the last-described form of head I pass a 8o pin e2 (shown inFig. l) throughsuitableopenings el e4 (see Fig; 10) in the spindle E and hub of the gear respectively. When the parts are thus connected., the machine may be i usedfor either curling the rim, beading the 85 body, or successively performing both these operations on vessels to' which a cover-piece may `have been previously attached.'

. Iffound cesi'rableahe seamingrons k' k' of the seeming-head may be removed and theA 9o places of the ones k supplied b y the groovcd curling-rolls i of the'lower head.

Either form of head'shown in Figs. 1,. 6, 7, 8,111, and 12 maybe used for seaming coverpieces to filled vessels; rbut for this class of 95 work I prefer touse the head described Ain -connection withFigs. 9 and' 10, in order that said head may be rotated around the vessel Vto thereby prevent the cont-ents of the-latter .from being splashed. roo

In the operation of my invention, where it Y is desired to curl` the rim, bead the body, and seam. a cover-piece thereon during one rotasv tion ofthe shaft D, said vessel is placed mouth downward on the lower head H and the s'tart- 105 Aing-lever F depressed. This depression of the lever starts the shaft D. The rotation of said shaftl causes the canrwheel G,fast thefreon, to rotate in the direction of the arrow, Figs. 1 and 5. By this means the roulet-ted .no is gradually disengaged from the" notch c in said wheel andthe lever G actuated to chuck the 'vessel while 'said wheel travels from y t0y 1 While the cam-wheel G is Vtraveling the ir 5 distance from y to y, Fig. 5, the .rotation of the vessel against the grooved rolls 'i in the lower head H will cause the rim of said vessel to be rolled in or curled, the lever N being actuated by the cam O onthe shaft D to set 12e crank T has in the meantime beentilted by the action of the cam-wheel V on'the shaft D to bring the seaming-rolls 7c k' into oper- 13o'.

ative position againstthe cover-piece, which Alatter in this case is the bottom of the vessel.

i The beveled portion of the 'roll k serves to' flatten the dange o f `the cover-piece down against `the vessel-bod (and for some urplainl portion f pressure causedbythe tilting of the rolls Ic k against tlie` ,\1pwa1'd` movement of the vessel (or by the'tiltingalone) turns the united cover- -piece and wall of `thevessel-body inward, as

shown by Fig.

` time being brought to the position illustrated in the same figure to support the seam thus turned in. Y

The seam formed as above described may "be either aslight'bend, right-angular bend,`a

direct opposition to the roll K on the shaft 1 wheelVto tilt back the bell-crank T, and the .3

curl, or a roll, according to the groove in the roll v said seam varying on different styles of .vessels The lever J s is now actuated by the cam Lon the shaft D to bring the roll or rolls AK into contact withthe vessel-body andginto whereby one or more beads are formed on said vessels body. When the shaft D comlotes its revolution, the roulette a on the sliding plate U comes into the notch of the eamroulett'e d on the lever G engages the notch c inthe cam-wheel AGf to unchuck the vessel. It will `benoticed that when the seaming- I head described ineonnection WithFigs. 9 and l0 is employed to rotate around the vessel the spring chuck or plate is always 1n advance of said head, as shown by dotted lines, Fig. 10,' andbythis means the cover-piece is held down upon the vcsseLbody againstthe action 1 ofA the rolls k andprevented from being dis-` placed by' the same `when irst coming into frictionaleontact therewith.

The head H may be secured to `the driving parts and the friction-brake My omitted, the

vessel being held by the operator during the time required for-rolling in or curling the Y rim, and when this operation is completed and said vessel released the latter will be ordinarily-rotated by its frictional contact with saidhead."

4The Aseaming. mechanism can be brought into play either automatically or by hand; or in some instaucesthis seami'ng mechanism may also be omitted and the machine used entirlyfor curling the rim and beading the bodyof the vessel. f

' It will be also understoodthat the vessels worked upon by my machine may be ehucked and rotated independent of -the curling, beading, or seaming mechanism above described, this operation being accomplished by depressing and holding down the foot-treadle Gi', itbeing impossibleto start'any one or all of said mechanisms until the lever F' is actuated.-l When the treadlc Gr is actuated as described above, the head II' may be held against rotation `f or a certain time, and the upward movement of said head against the 7,the wheel k2 at the same wenn rotation of the vessel will cause the rolls t to perform the curling operation.-v

The head or lever carrying the lsearningrolls may be held in a lixed position, or, in"

other words, the tilting mechanism may bedisconnected therefrom. In this case, or for doing either one of the latteroperations, the

vessel is forced up bythe movement of vt-he lower'chuck to come against the' seamingrolls, the chuckon the livespindle being, as

before stated, in advance of said rolls to prevent displacement of the cover-piece.

I do not wish to be understood as broadly claiming seaming and flattening rolls ar' -.ranged in a. head at an angle to eachothenas I limit myself to a .combination capable of eiecting the seam claimed in my patent, No. 359,826, as above recited.
